An up to date and humble explanation of the extinction of dinosaurs in North America. Though some who refute current theories about the Chicxulub crater claim there was no cause and effect, at least this one acknowledges that it certainly played a role - it is the overall impact that is to be discussed. Otherwise, one could not explain an alternate reasoning as to why there was such a mass extinction of dinosaurs. Dlodh574 (talk) 01:01, 9 April 2012 (UTC)

Which organisms specifically were studied? The proposed meteorite that may or may not have caused the extinction of the Dinosaurs did not cause the extinction of all life on Earth - did this study include the extinction rates of other species during this era?Cyabl420 (talk) 00:40, 11 April 2012 (UTC)

Dinosaurs were killed off in a relatively short period of time which appears to have been triggered by the period of global warming and devastation caused by a meteorite. Bomor394 (talk) 05:36, 18 April 2012 (UTC)

The dinosaurs were killed from the meteorite and not from volcanoes because we humans have been around for a long time and volcano has not eruptured hard enough to kill all human on the planets, the bones of the dinosaurs in the ground proves that it is the meteorite's work because a volcano is hot enough to burn off bones that was remaining from the dinosaurs.Bomor394 (talk) 05:36, 18 April 2012 (UTC)
Dinosaurs in North America became extinct in a geological instantaneous way. Which means this extinction occurred over the course of tens of thousands of years.Mcder (talk) 01:27, 26 September 2012 (UTC)



the researchers technique is proven by how deep the bones are in the earth and how old the bones are when they are found, all of these comes to a conclusion that states the extinction of the dinosaurs.Bomor394 (talk) 05:40, 18 April 2012 (UTC)


The patterns of survival are not verifiable when compared to an asteroid impact. The continuation of life, such as species whose diet was detritus-based, should not have survived when events such as wildfires, acid rain and atmospheric dust are considered.Nitoryu (talk) 01:34, 26 September 2012 (UTC)


It is important to note that shelter during this event would have been more important than a detritus-based diet. While shelter could not guarantee protection from the global event, species that would find themselves without shelter would be exposed to lethal levels of heat and exposure.Nitoryu (talk) 01:35, 26 September 2012 (UTC)

Extinction of the dinosaurs by climate change is very possible. We can see evidence today of quick changes in an environment having an impact on life. Migratory birds are threatened because wetlands are drying, warmer temperatures in the arctic are threatening the polar bears. Unfortunately there seems to be little evidence as to what may have caused the quick change.Tlouc287 (talk) 17:25, 13 April 2012 (UTC)
